Galaxy Performance SDK' PerformanceManager returns null on new devices

Hello!

I’m investigating background work issues on Samsung with our app and have found Galaxy Performance SDK.
But PerformanceManager.getInstance() returns null on some devices like S22 or Xcover Pro, but returns an instance on Galaxy A20e.
Is it expected behavior or a bug?
And does this SDK work with Android 12?

Did you check the sample application that has been attached with the SDK?
If not, you can run sample application to check whether it is working in android 12 devices or not.

Yes, I checked it, but it doesn’t have build.gradle files, so I couldn’t build it.
Anyway, I, basically, copied MainActivity to an empty project and SDK returns null Android 12 devices.
